Hello,
I have a vb net application connected to an sql sever database, I use a query to search records and display them to a datagridview, I use crystal reports to print, I can't make it print the selected rows of the datagridview, it prints all the result records, how can I pass multiple number values to a crystal report selection formula?

Dim rpt1 As New CrystalReport1()
       rpt1.SetDataSource(DataSet31)
       rpt1.ParameterFields.Item("ID").CurrentValues.AddValue(Me.DataGridView1.SelectedRows(0).Cells(0).Value)
       Form6.CrystalReportViewer1.ReportSource = rpt1
       Form6.Show()

dataset31 the query dataset, rpt1 the crystal report .rpt
even if I add a single value prints all

rpt1.ParameterFields.Item("ID").CurrentValues.AddValue(11)
